Festo
The Festo 8111611 is an externally controlled 2/2 poppet valve with a piston actuator designed for in-line installation in any mounting position with a 1 1/2 ANSI/ASME B 1.20.1 threaded sleeve cable connection and a G1/8 internal thread pneumatic connection. Featuring a non-reversible flow direction under the valve seat for gaseous and liquid media, it handles a medium pressure range of 0 MPa to 0.93 MPa, a Kv flow rate of 32.9 m³/h, and a maximum viscosity of 600 mm²/s across medium temperatures from -10 °C to 180 °C. The unit operates via pneumatic actuation requiring an operating pressure of 0.5 MPa to 0.7 MPa using filtered compressed air as per ISO 8573-1:2010 [7:4:4], utilizing a mechanical spring reset method for on/off operation in weather-protected exterior locations classified as class C1 based on IEC 60654-1.
